how to change serial number in bios lenovo g580

What is the reason for this problemchange in bios v2.3 and will this be fixed in future versions Is this a known problem with newest bios When people will buy this MB and it has v2.3 from factory the smart fan control will not work properly and buyers will not know how good it can acctually be.

Other Lenovo Motherboard have Restrictions for controlling the Fan.

But give it a shot If it detected your fan then youre all set.

Change In Bios Lenovo G580 How To Use That

But so far I have not been able to find out how to use that feature.

AFAIK, some earlier Lenovo models did have a separate touch button for this feature.

Is the user supposed to be able to control it at all in G580 There isnt anything about this in the user manual.

Change In Bios Lenovo G580 Software Gives Me

Lenovo Energy Management software gives me some kind of control over the efficiency of the hardware.

But to me it just seems to replicate the selections I make with Windows own power management options.

However when reading the user manual, or looking at the laptop itself it is abundantly clear that THERE IS NO NOISE CONTROL BUTTON.

Clearly the reply saying the original post has been solved was in error.

Normally I would be ok with that if you had bothered to fix it or apologize for some kind of clerical error by now.

I dont think, but KNOW that you need to either admit the G580 doesnt have the features in question or explain how we can useaccess them.

If you cannot resolve something this SIMPLE, what should I expect if I have a serious problem Well, I dont want to have to find out.

If this thread doesnt get either an ACTUAL informative response, or a simple apology I will return my laptop.

I will advise everyone I can, whis is substantial as I work 6 days a week doing home and buisness tech support, not to purchase lenovo products.

I do not have long until my 30 day window expires to return it.

I have been waiting for a response to this since I bought it.

At first the motherboard had v2.0 Bios and everything worked just fine but as i like maximum compatability and other fixes i upgraded the bios to the latest one v2.3.

In my setup i use the bios smart fan control for both system and CPU fan, i set it at a curve where the fans instantly will rise the fan speed when doing tests like Prime95 and Aida64.

When doing the tests the fan rised from idle 800rpm to neded fanspeed for the correct cooling for my CPU and reached maximum 1500rpm in a matter of seconds to keep the CPU cool.

This worked perfectly with Bios v2.0 but after i upgraded the bios to v2.3 the smart fan control changed fanspeed extremely slowly, it took almost 50sec for the fan to speed up from 800rpm to 1500rpm when stressing the CPU at 100.

When i stoped the stress test the fans slowed down to idle 800rpm very fast with bios v2.0 but with bios 2.3 i took a looong time to slow down to idle speed again from 1500rpm.

Because of the slow changing fanspeed in bios v2.3 i downgraded to v2.0 again and then my fans works just as i want them to do.
